I am selling my PW-1, it is a later model sn that does not require the amp to be on to switch antennas. It is in very nice condition with original box, manuals, accy. It works flawlessly and has 10/12M enabled. Asking $3600 plus 1/2 shipping. Gary Mitchelson N3JPU Davidsonville, MD FM18 http://www.mitchelson.org/
